The boy initially presented with borderline sized left-sided heart structures, congenital left AVV stenosis, ventricular displacement of the right AVV with high-grade insufficiency and moderate valvar pulmonary stenosis. Double AVV replacement was performed 2 months after an unsuccessful attempt to repair the defect with persisting left AVV stenosis, underfilling of the small left ventricle and high-grade right AVV, and pulmonary valve regurgitation, resulting in low cardiac output. During double Melody\u2122 AVV replacement, the right ventricular outflow tract was replaced with a pulmonary homograft. The boy was discharged on post-operative Day 28 and presented with competent valves, no ventricular outflow tract obstruction and no paravalvular leak at 11 months of follow-up.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>The presented innovative approach allowed for biventricular correction of an unbalanced AVSD with unfavourable anatomy for standard techniques. The heart team should decide individualized, after careful assessment of cardiac anatomy and function, if the benefits of replacement of AVVs with Melody\u2122 transcatheter valves may outweigh the benefits of univentricular palliation in case of unbalanced AVSD.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaa174","type":"journal-article","created":{"date-parts":[[2020,8,5]],"date-time":"2020-08-05T21:16:09Z","timestamp":1596662169000},"page":"1-6","source":"Crossref","is-referenced-by-count":1,"title":["Double atrioventricular valve replacement using Melody\u2122 transcatheter valves in an infant with unbalanced atrioventricular septal defect: a case report"],"prefix":"10.1093","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8462-0295","authenticated-orcid":false,"given":"B\u00e9atrice Susanne","family":"Kahl","sequence":"first","affiliation":[{"name":"Division of Pediatric Cardiology, Pediatric Heart Center Vienna, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, Waehringer Guertel 18-20, A-1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3131-573X","authenticated-orcid":false,"given":"Ina","family":"Michel-Behnke","sequence":"additional","affiliation":[{"name":"Division of Pediatric Cardiology, Pediatric Heart Center Vienna, Department of Pediatrics and Adolescent Medicine, Medical University of Vienna, Waehringer Guertel 18-20, A-1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2185-4895","authenticated-orcid":false,"given":"Daniel","family":"Zimpfer","sequence":"additional","affiliation":[{"name":"Division of Cardiac Surgery, Pediatric Heart Center Vienna, Department of Surgery, Medical University of Vienna, Waehringer Guertel 18-20, A-1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,8,5]]},"reference":[{"key":"2020101507251077800_ytaa174-B1","doi-asserted-by":"crossref","first-page":"565","DOI":"10.1093\/ejcts\/ezx129","article-title":"Mid-term outcomes in unbalanced complete atrioventricular septal defect: role of biventricular conversion from single-ventricle palliation","volume":"52","author":"Nathan","year":"2017","journal-title":"Eur J Cardiothorac Surg"},{"key":"2020101507251077800_ytaa174-B2","doi-asserted-by":"crossref","first-page":"e007145","DOI":"10.1161\/CIRCINTERVENTIONS.118.007145","article-title":"Surgical atrioventricular valve replacement with melody valve in infants and children","volume":"11","author":"Pluchinotta","year":"2018","journal-title":"Circ Cardiovasc Interv"},{"key":"2020101507251077800_ytaa174-B3","doi-asserted-by":"crossref","first-page":"615","DOI":"10.1161\/CIRCINTERVENTIONS.111.963389","article-title":"Short-term performance of the transcatheter Melody valve in high-pressure hemodynamic environments in the pulmonary and systemic circulations","volume":"4","author":"Hasan","year":"2011","journal-title":"Circ Cardiovasc Interv"}],"container-title":["European Heart Journal - Case Reports"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/ehjcr\/article-pdf\/4\/4\/1\/33889404\/ytaa174.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/ehjcr\/article-pdf\/4\/4\/1\/33889404\/ytaa174.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,10,15]],"date-time":"2020-10-15T11:38:30Z","timestamp":1602761910000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/ehjcr\/article\/4\/4\/1\/5881465"}},"subtitle":[],"editor":[{"given":"Christoph","family":"Sinning","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]},{"given":"Inga","family":"Voges","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]},{"given":"Sylvia","family":"Krupickova","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]},{"given":"Stefan","family":"Simovic","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]},{"given":"Vishal Shahil","family":"Mehta","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2020,8,1]]},"references-count":3,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2020,8,5]]},"published-print":{"date-parts":[[2020,8,1]]}},"URL":"https:\/\/doi.org\/10.1093\/ehjcr\/ytaa174","relation":{},"ISSN":["2514-2119"],"issn-type":[{"type":"electronic","value":"2514-2119"}],"subject":[],"published-other":{"date-parts":[[2020,8]]},"published":{"date-parts":[[2020,8,1]]}}}
